Subzero: Cleanup Inst==>Instr.
In the beginning, Ice::Inst was called IceInst, and patterns like "IceInst *Inst = ..." made perfect sense.
After the Ice:: name change, "Inst *Inst = ..." continued to compile, mostly.
However, shadowing a type name is clumsy and newer code tends to use "Inst *Instr", so we might as well switch all the instances over.
Some are still called "I" and those are left alone.
